I am about to install a new fuel pump. I need to hear from the guys that cut the access panel in the rear above the tank. Anything you would suggest or advice you could give me? I ordered the Granatelli 255 LPH pump from Summit. I got a new pressure regulator and some 30 lb/hr injectors too. My ported heads I'm gonna install next spring after I get back from Army duty will love the 30lb/hr injectors I hope. I ran a 7.92 1/8 a few weeks ago when my pump went bad. Starting had been hard for a while too. The pressure jumped up to 30 lbs, then immediately to 15 lbs at turn of key to on but not start. Bad. The car was idling at 33 lbs pressure at the schroeder valve. Bad again. I guess this will cause it to run lean? Bad. Has anyone else used the Granatelli fuel pump. I have only heard from 2 guys so far and they said it was doing OK. Thanks,, sorry for long post.

 

i want to hear more also about cutting a access hole

 

Yeah I'm wondering what they used to cut the panel with. A jigsaw might cut fuel lines looks like.

 

dremel tool and this site.

i just got done replacing my fuel pump. i cut the hole with a dremel tool it was real easy

 

I used my air compressor and a cut off tool. Much quicker than a dremel but much more care must be taken so you don't cut too deeply. There are lots of how to guides to making the hole. The only pain was disconnecting the fuel lines.

 

You didn't mention if you tried changing the fuel filter? A 93 that hasn't had the fuel filter changed probably needs it

 

If you have access to air tools I would recommend the air powered cut-off wheel. Just remember if you smell gas, then you may just want to use tin snips.

I installed a Granatelli about a year ago and so far it has worked trouble free.

 

I got the access panel cut. Started with Dremel and then used sheetmetal shears to cut panel and open it all up for easy access. Now I have got to remove those little bolts around the perimeter of the circle right? Then what? How did you get the fuel lines off and are they very flexible?

also: does anyone know the guy with the black SS that is doing all the burnouts on video he titled "feel the power"? The listing just says "dans_new_video." I want a copy of that on CD and I'll pay for it if I need to. I bet he wasted 4 sets of tires on that 3 minute mpeg or whatever it is.

 

Yup you need to remove those bolts. But first I would disconnect the fuel and electrical lines. The small fuel line you just need to pull it off, there shouldn't be any clamps. The other 2 follow them forward down the front of the tank until you find the connectors. They are not very easy to get at, I ended up cutting the panel out bigger to get at them. The electrical connect or is easier to get at from under the car, it is in front of the tank to but is lower down.

I had a little trouble getting the fuel lines disconnected but the real problem was pushing them back together (since the line flexes) when I put the pump in. So if you are having trouble disconnecting them cut the panel bigger because it will make the install that much easier.

Hopefully I am remembering all of this correctly since it has been over a year since I did it. Also I don't think your 93 is different from my 95 but I don't know for sure.

 

Just cut my panel yesterday... used air compressor and die grider with cut off wheel.... drilled a small 1/2 hole first with my drill at the back right passenger side corner and then started with the die grinder cutting a bit stopping, cut a bit stopping.. took less than an hour to do.

 

OK. I have gotten all fuel lines disconnected.
ADVICE!!: Cover edges of cut metal with duct tape or something like that. I didn't , and guess what!?..........yep......ow!
So now Ive got to find the electrical connector down in front of the tank. I disconnected my neg. battery terminal too j.i.case. A little gas came out of the forward line with the fitting on it. not much. I can see where those fuel line clips could be broken easily so got to be careful with them. seems like if you get them pressed in and keep a little pressure on them with a screwdriver, they stay pushed in sop you can pull the connection apart. The 2 lines with the connectors seemed like they were not that hard to get disconnected after the clips were pressed in.
I am gonna draw a pic and diagram all this stuff so it goes back together correctly. I am gonna take digital pics too..I'll try to post. later. progress is being made regardless!
Now Ive got to find a big bandaid!

 

I got it all fixed and the car started fine after a few turns of the key to prime the lines. Seems like the Walbro is a little louder than the stock unit. Maybe it is because it is not under a metal panel yet though. I left my panel off to check for leaks. No leaks.
I used epoxy resin to put the pump plastic container back together. I read all the directions and info sites but they left out alot of details. I had to stop several times because of rain since I was not in garage. It was not a real difficult job. It made it easy just to be able to sit in the trunk of the car most of the time to do the work. Outside working is better if you can because of gas fumes. Try to run as much gas out of the tank as you can if your car is able before you do this replacement. I also had replaced my fuel filter 2 months ago. Do this along with the pump if you can. Clean around retaining ring before you removed it to make sure no dust or junk falls into your tank. A can of carb cleaner works great on cleaning top of tank pump removal area. Remember to remove battery Neg. cable. The electrical connector you will have to use a floorjack or somethig to get under the car. The plug you're looking for is infront of the driver's side axle. Kind of outside the bottom of the body behind the drivers side back seat. There are 2 plugs stacked there. Unplug the bottom one, it has a clip on the bottom of it. It is the fuel pump power, you'll see it. The hard plastic felx line on the old pump will not come off I guess. I used a 5/16 EFI hose I got from Auto Zone and used that in place on my new pump. The rubber piece they put in the install kit that goes around the pressured gas sending tube will have to be trimmed a little with some scissors to fit just right. I didn't cut my wires like the instructions said. The plug that comes with the Walbro fits and adapts the Factory wires to the Walbro unit. Let the glue (I used Marine Epoxy from WalMart, in the auto paint/body work section by Bondo) set a while when you put the yellow plastic box back together. Be careful taking it apart too. Small screwdriver to pry lid off of it. Goes back together otherwise like it came apart. Good luck!

 

I am just about there too... got the pump out and new pump put together. Let the glue to the bucket cure overnight and will be going in today. Routed wiring harness yesterday, pretty easy install so far. Will update today when i fire her up.

 

If you get some pictures up, that would be great!!
